Specification of Letters Patent.

Patented. June 25; 1912 Application filed May 17, 1905. Serial No. 260,840;

To all whom it may concern Be it known that I, CHARLES E. IIOWE, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain Improvements in cementing-Machines, of which the following description, in connection with the accompanying drawings, is

a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes and particularly to machines for applying cement to the channel and to the face of the upturned channel flap of a shoe sole for the purpose of causing the flap to adhere to the surface of the channel when said flap is laid into its original position for covering the line of fastenings which secures the sole to the upper or the welt of the shoe.

One of the objects of the present invention is to provide novel means for guiding the shoe with relation to the cement applying means, whichis herein shown as a rotary brush and will be referred to as a brush, although the particular means used for applying cement is not material to the invention. It is very important in this class of machines that the work shall be sopresented to the ce ment applying brush that the surfaces to be united may be thoroughly coated with cement without liability of any other portions of the shoe, particularly thesole, being 35 smeared with the cement. Smearing of the shoe with cement is objectionable not only because of the obvious waste of cement which it occasions, but especially because of the time and labor required for removing such cement. A particular dilficulty is encountered when soles are to be finished to present a light color. The soles require to be wet for rendering the channel flap pliable so that it can be laid back over the channel "into its original position for covering the line of stitches in the channel and this wetting has to be done after the cement has been applied to the surfaces to be united. It is found in practicethat any spots or smears of cement on the face of the sole prevent the absorption of water by the portions of the sole so covered and cause spots or water stains as they are called, which are not removed in the operation of finishing the sole. While stains are not objectionable on a sole finished by blaoking or painting, it is always important that no cement shall get over the edge of the flap to stick it to the sole, because if the flap is stuck to the sole the water does not get to .the flap to moisten it and render it pliable enough to be laid back into the channel without danger of breaking the flap.

lVith these considerations in view therefore a very important feature of this invention consists in providing means by the aid of which the shoe may be so guided to the cement applying brush as to avoid liability of cement being applied to portions of the shoe on which it is not desired. Said guiding means preferably includes means, independent of the cement applying means, for engaging the sole on the inner side of.the channel by which the position of the shoe with relation to the cement applying means may be gaged as the channel flap and channel are presented in position to receive cement. In the embodiment of the invention herein shown said guiding means is arranged to be positioned for requiring the shoe to be presented with the sole in a plane inclined downwardly and outwardly away from the machine and which is therefore oblique to the plane of the acting face of the cement applying means. Said guide will thus insure that when the channel and flap are presented to the brush the face of the sole at the outer side of the brush will occupy a plane below the acting face of the brush. The face of the sole, therefore, will not be liable to become smeared with cement even if the brush should extend over the edge of the channel flap.

A further object of the invention is to support the edge of the channel flap away from the face of the sole and in the path of the brush while the cement is being applied to the flap and channel. The flap is often pressed down close to the face of the sole when it is turned back from the channel and when in this position it is exceedingly difficult to coat the flap to its free edge without getting cement on the adjacent port-ions, of the face of the sole. Another difficulty in thoroughly coating the flap is that the flap is frequently crimped or wrinkled, espeoially at the port-ions where the flap is turned inwardly from very convex edge, as at th'etoe and sometimes at the inner side of the shank of the sole. When in this condition there will of course be portions of the flap which will not be coated by the brush. By lift-ing the flap from the surface of the sole the crimps or wrinkles are partially straightened out so that the surface of the flap may be much more thoroughly coated than could otherwise be done.

7 Another important feature of the invention, therefore, consists in providing means arranged to support the overturned channel flap of a channeled sole away from the underlying surface of' the sole and preferably in the path of the brush while cement is beingapplied to the flap. This enables the operator to coat the flap with cement to its edge without the adjacent face of the sole being brought into close proximity with the cement brush. Preferably said supporting means will be constructed and arranged to lift the flap in the event that the flap lies close to the face of the sole and in lifting the flap to tend to straighten out crimps or wrinkles therein. The flap may then be so thoroughly coated wit-l1 cement that no difficulty will be experienced in causing the wrinkled portions to adhere to the surface of the channel when the flap is laid over the channel to cover the line of fastenings therein. r The means for lifting and supporting the channel flap is, in the embodiment of the invention herein shown, the guiding means before described for engaging the sole on the inner side of the channel. Said means which engages the sole and extends under the channel flap will preferably be 7 arranged to contact with the work at a point at one side of the vertical plane in which the axis of the brush extends whereby the shoe may be rocked in the direction of the length of the channel to press the surfaces to be coated with more or lessforce against the brush. Preferably the portion of said guiding means which extends under the channel flap will be shaped to enter the angle between the flap and the face of the sole and to engage the sole at the base of the channel flap, whereby said base of the channel flap will form the point of contact. with relation to which the shoe is guided laterally. Said guiding means will thus contact with the work at a point which is located in a plane between the sides of the brush and about which the shoe may be rocked transversely of the surfaces being coated, as well as longitudinally thereof, to present these surfaces in desired relation to the acting face of the brush. This arrange ment is advantageous because the channel flap and the surface of the channel present an irregular contour which varies according to the turned over position of the flap and for the best results the position of the shoe should be varied according to the contour of'the surfaces being coated. In the pre ferred embodiment of the invention the guiding means is arranged for adjustmentinto position for guiding the work normally at a suitable altitude with relation to the acting face of the brush and is constructed to yield for permitting the shoe to be pressed closer to the brush when desired and also to permit the lateral position of the shoe to be varied.

Other features of the invention, including certain details of construction and combinations of parts, will be hereinafter described and pointed out in the claims.

Figure 1 is a side elevation of a portion of a cementing mechanism to which the present invention has been applied. Fig. 2 is a perspective view of shoe guiding means and of a portion of a shoe in operative relation to the guiding means. Fig. 3 is a front elevation of a portion of the cement applying a brush and of a shoe, the shoe guiding means being shown in section on the line 33 of Fig. 1.

The cement applying machine comprises a frame 2 to which is secured a supply pipe 4, the cement being delivered from the supply pipe through a conduit to a discharge opening 6, which is normally closed by a valve controlled by a manually operated lever 8. The frame is provided with a hearing for a shaft 10 to which is secured a pulley 12 and a brush 14, although it is to be understood that any other form of cement applying means may be employed instead of the brush herein shown. The brush is located under the outlet 6 to receive cement therefrom and is rotated for applying the cement to the surfaces to be coated, which are herein shown as comprising the channel and the upper face of the overturned channel flap of a shoe sole.

The guiding means, which in accordance with this invention is provided to assist the operator in so presenting the channel and channel flap that these parts may be thoroughly coated with cement without liability of other portions of the shoe being smeared with cement, comprises in the embodiment of the invention herein shown a device 20. The guiding device has an attaching portion 22 carrying a clamping screw 24, which extends through a slot indicated by dotted lines in a depending portion 26 of the frame 2. The guiding device may be secured by the clamping screw 24 in different vertical posit-ions according to the size of the brush or the requirements of the work, the altitude of the work engaging end of the guiding device determining in part the plane in which the face of the sole will be heldrelatively to the plane of the acting face of the brush in order to present the channel and flap properly to the brush. The guiding device also includes, as hereinshown, a horizontal member 28 andv a depending shank portion 30 extending on the outer side of the brush. On

might be separately formed and removably secured to the shank. The work-engaging member 32 is arranged to contact with the sole of the shoe at a point adjacent to the place where the brush is acting on the surface of the channel and the overturned channel flap and preferably positions the shoe so that the face of the sole will be inclined outwardly and downwardly from the cement applying brush, and the portion of the sole inside the marginal channel will be oblique to and below the plane of the acting face of the brush. Preferably the work-engaging member is constructed and arranged to extend under the channel flap and so engage the sole at a point below the brush. The engaging member is also preferably shaped to contact with only a small area of the sole and to constitute in effect a bearing about which the shoe may be rocked transversely of the channel to incline the face of the sole more or less with relation to the plane of the acting face of the brush according to the contour of the surface being coated with cement. It is found in practice that sometimes the channel flap is turned over upon the shoe sole to lie very closely against the sole while in other instances the flap stands considerably away from the sole so that the contour of the surface to be acted upon by the brush varies in different shoes, and, it may be, in different parts of the same shoe. Preferably the member 32 will engage the base of the channel flap as has been suggested and thus determine the lateral position of the shoe with relation to the brush.

In addition to its function as a guide for determining the vertical position of the work with relation to the brush, and it may be the lateral position also, the member 32 serves to raise the channel flap from the face of the sole if the flap has been turned over to lie close to the sole. The guide also sustains the flap away from the sole adjacent to the point where the brush is acting and supports it against the pressure of the brush so that the flap may be coated with cement quite to its free edge without danger of the cement getting over the edge of the flap and upon the face of the shoe solo. The guiding member 32, by lifting the channel flap, partially straightens out and opens the folds or crimps which are found in the flap at the toe of the shoe and at the other portions where the flap has been turned in wardly from a convex edge. This allows the flap to be more thoroughly coated with cement than is otherwise possible. It will be noted that as herein shown the guide extends downwardly along the side of the brush and then laterally to a point under the brush as shown in Fig. 1. A portion of the guide thus extends between the brush and the face of the sole and may, if of suflicient width, protect the sole from liability of cement from the brush getting over the edge of the flap and falling on the face of the sole. Preferably the guide will be constructed and arranged to present a firm abutment for determining the normal position in which the shoe shall be presented to the cement applying brush but will be arranged to yield in response to unusual pressure for permitting the work to be pre sented in different positions with relation to the brush. As herein shown the horizontal member 28 of the guide is provided with a reduced portion 3a, or is otherwise made resilient. This permits of the guide yielding to upward pressure and also to lateral outward pressure, whereby it may assume the positions indicated by the dotted lines in Fig. 1.

Preferably the guide will be positioned with relation to the brush to engage the work somewhat at one side of the vertical plane in which the axis of the brush is located as shown in Fig. 3. This allows the work to be rocked in the direction of the length of the channel for the purpose of pressing the work with more or less force against the brush without requiring the guide to yield. Another advantage for thus locating the guide at one side of the point where the brush acts on the work is that it is thereby located slightly without the path of the brush and the cement is less likely to get from the brush on to the guide when no shoe is in position to be cemented. It is of course desirable to keep the guide free from cement to avoid the liability of smearing the face of the sole with cement from the guide.

Having disclosed the nature of the invention and fully described a construction embodying the several features thereof, I claim as new and desire to secure by Letters Patent of the United States 1. A machine for applying cement to the margin of a sole having in combination a cement applying member and a guide, said guide comprising'a flat bar having two bends of approximately ninety degrees each, a portion of said bar being of reduced cross section to provide resiliency.

2. A machine for applying cement to a channeled sole having in combination a cement applying member, and a guide for engaging the base of the channel flap, said guide comprising a curved resilient bar.

3. A machine for applying cement to a channeled sole having in combination a cement applying member, a guide for engaging the base of the channel flap, said guide comprising a curved resilient bar, and means whereby said bar may be adchanneled sole havin in combination, a

justed to move its operative portion toward and from the cement applying member.

4. A machine for applying cement to a channeled sole having, in combination, a cement applying member and a guide for engaging the channel flap, said guide comprising a base attached to the frame on one side of the cement applying member and a portion extending around said member to the other side thereof.

5. A machine for applying cement to a cement applying mem er and a guide for engaging the channel flap, said guide com-.

prising a bar having a resilient portion extending obliquely downward whereby "upward pressure of the shoe against'the channel-flap engaging end of said guide causes said end to move laterally as well as upwardly.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. 7
